An Elysee taxi, after driving, does not dare to use the air conditioner. Once the air conditioner is opened, there is no idle speed after the fire is extinguished. It is necessary to disassemble the negative electrode line of the battery to recover the idle speed. For this kind of fault, the repair is repaired, and all the changes have been replaced, and many shops have not been repaired. In fact, the basic reason for the failure of the car is that the power supply capacity of the whole vehicle is insufficient to see the table. The user and the maintenance plant can not be solved, and the manufacturer has already realized this problem. Under the existing conditions, the driver can only clean the throttle regularly to ensure a good charge and keep the car in good technical condition to cope with the shortage of power supply for the whole vehicle.
